Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of copper-zinc brass alloy instead of bronze
Brass alloys where zinc predominates over other elements (note a) fall under copper alloy strips excluding bronzes.
If of refined copper without tin alloying
Pure copper or non-alloyed copper strips classify under unalloyed copper headings.
If width 500mm or greater
Same bronze composition but exceeding 500mm width moves to wider strip subheading.
